Description

Technical Field

[0001] This utility model relates to the field of pencils, and more particularly to a pencil with a photosensitive color-changing effect. Background Technology

[0002] A pencil typically consists of a shaft and a lead. The pencil is held by the shaft and the exposed lead tip is used for writing or drawing. To enhance the aesthetics of the pencil shaft, a layer of colored paint can be applied to the outside.

[0003] The paint on the surface of a pencil usually does not change color. To increase the fun, photosensitive color-changing paint can be used. Photosensitive color-changing paint uses ultraviolet light to excite molecular energy level transitions, changing the light reflection characteristics, thereby achieving the effect of photosensitive color change, which helps to enhance the user's interest. However, photosensitive color-changing paint is expensive, and after being applied to the surface of the pencil, it falls off during the pencil sharpening process, resulting in serious waste, and needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a pencil with a photosensitive color-changing effect, which increases its fun and reduces costs.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A pencil with a photosensitive color-changing effect includes: a pencil barrel, a pencil lead, and a photosensitive color-changing part. The pencil lead is concentrically disposed in the pencil barrel. The photosensitive color-changing part includes a slider and a photosensitive color-changing coating disposed on the outer side of the slider. At least one side of the outer wall of the pencil barrel is provided with a groove corresponding to the slider. The groove extends along the length direction of the pencil barrel. The slider is slidably and adjustablely disposed in the groove.

[0007] The photosensitive color-changing coating is a layer of photosensitive color-changing paint.

[0008] The number of sliders in the groove is at least one.

[0009] The groove is a dovetail groove.

[0010] The slider has elastic rubber strips on both sides that make elastic contact with the inner wall of the groove.

[0011] The slider has recessed positioning grooves on both sides corresponding to the elastic rubber strip. The elastic rubber strip is placed in the positioning grooves and fixed with glue.

[0012] The slider is a strip-shaped wooden or plastic block.

[0013] The beneficial effects of this utility model are as follows: A pencil with a photosensitive color-changing effect is specially designed with a photosensitive color-changing part that can be slidably adjusted and separated. This not only achieves the photosensitive color-changing effect and enhances the user's interest, but also allows for reuse and reduces costs. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model;

[0015] Figure 2 yes Figure 1 A top view from angle AA. Detailed Implementation

[0016] The following is combined Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0017] like Figures 1-2 The pencil shown has a photosensitive color-changing effect, including: a pencil barrel 1, a pencil lead 3 and a photosensitive color-changing part 2. The pencil lead 3 is concentrically arranged in the pencil barrel 1. When holding the pencil barrel 1, one can write or draw using the sharpened pencil lead 3.

[0018] The photosensitive color-changing part 2 includes a slider 21 and a photosensitive color-changing coating 22 disposed on the outer side of the slider 21. In this embodiment, the photosensitive color-changing coating 22 is a layer of photosensitive color-changing paint. It uses ultraviolet light in the light to excite molecular energy level transitions and change the light reflection characteristics to achieve the effect of photosensitive color changing, thereby enhancing the user's interest.

[0019] In this embodiment, the slider 21 is a strip-shaped wooden or plastic block, which has a stable structure, can be reused, reduces the cost of use, and avoids the waste of the photosensitive color-changing coating 22.

[0020] like Figure 2 As shown, at least one side of the outer wall of the pencil barrel 1 is provided with a groove 11 corresponding to the slider 21. The groove 11 extends along the length direction of the pencil barrel 1. The slider 21 is slidably and adjustablely disposed in the groove 11. The slider 21 can slide upward as the length of the pencil barrel 1 changes during use without damaging the slider 21.

[0021] The number of sliders 21 in the groove 11 is at least one. In this embodiment, 2 to 3 sliders 2 are used. As the length of the pencil rod 1 decreases during use, the uppermost slider 21 is removed to avoid the problem of the slider 2 extending too far out of the pencil rod 1.

[0022] like Figure 2As shown, the groove 11 is a dovetail groove, and the slider 21 has a trapezoidal cross-section. The groove 11 guides the slider 21 during its up-and-down sliding adjustment, preventing it from slipping off. Furthermore, to prevent the slider 21 from slipping down, elastic rubber strips 4 are provided on both sides of the slider 21, which elastically contact the inner wall of the groove 11. These elastic rubber strips 4 increase frictional resistance, providing elastic restraint for the slider 21 and ensuring high stability during writing.

[0023] In this embodiment, the slider 21 has recessed positioning grooves 23 on both sides corresponding to the elastic strip 4. The elastic strip 4 is placed in the positioning grooves 23 and fixed with glue to prevent the elastic strip 4 from falling off from both sides of the slider 21.

[0024] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
